SPECIFICATION forming part of Letters Patent No. 386,116, dated July-5, 1887.

Application ill-n1 \pril in, 1837. Serial No. 233,092. (No model.)

To all whom it may cnncern' Be it known that I, ERNST Kon'rmo, asuhject of the King of Prussia,.rcsiding at Hanover, in the Kingdom of Prnssia Ger many, have invented new and useful Improvements in Gas-Motors'whcreof the following is especifieation. My invention relates to gas-motors inwhich, when the speed is too great} the governor opro crates to keep open the exhaust-port, s0ithat.

,the piston then pushes the combustion-gases from the cylinder into the exhanstpipe and draws them back again without sucking in combustible gas mixture.

The first improvement consists in means for establishing a connection between the exliaust-valve and the induction-valve for combustible gas mixture, whereby when the exhaust-valve is open the induction-valve will be .kept closed, in view of preventing an entrance of gas mixture into the cyliuder,whcreaswhen the exhaustvalve is closed the operation of the induction-valve is unimpeded. v

The second improvement consists in the 2 5 means employed, in combination with the'governor, for keeping open the exh mist-valve when the speed of the engine isabove the normal.

0n the annexed sheet of drawings is repre scntcd the frame of a gas-engine having at- 0 Hundred to it the valve-operating mechanism in volviug my improvements, the val ve-hoxes being shown in section.

- a is the portion'of the frame containing-the power-cylinder; b, the crank-shaft.

c d are the gear-wheels for driving the shaft carrying the tappet e.

g is a. valve by means of which gas and air are mixed .in determinate proportion ;.p, the valve for the admission of gas mixture into the cylinder, the said valve being provided with a springfor closing thesam'e, but for the rest operating automatically; 'm, the exhaustvalvei which isopened by thetappet e and intermediate parts and closed by a spring; and 1, an electric igniting device. The said intermediate parts (shown by the drawing) con sist in the roller f, carried by a. guiding-arm, k, the lever 11., to which is connected the rod 1 of the exhaust-valve m, the spring 2, acting 5o connecting together the arm I; and the lever h.

from helow against the lever h, and the rod 9,

For estabi ishing the aforesaid connection be tween the exhaust-valve m and theinductionvalve 1) a double-armed lover, a, is inserted betweenthe respective rods or stems l and o v or is'closed. According to thedrawing, the

lever, having its fulcrum at n, is pivoted with one end to the rod 1, so as to be positively oscillated thereby, whereas with itsother end,

which is forked, it projects under the collar 0 of the rod'o, there being so much play between this end of the lever and the collar 0 that when the valve m is closed the lever. allows the rod 0 to moge, while when the valve m is fully open the lever bears against the collar 0 and keeps the rod in its uppermost position. In order to avoid undue strains, the connection 'between' the parts in question is preferably made resilient-4hr instance, in forming the end of the lever-n operating upon the rod 0 by a'spring, as shown in the drawings. I

The means forkeeping open the exhaust valve whenever and as long as the engine runs too fast consists in a pawl, '8, having its fut cram at 1'0, and connected by an arm, z and a rod, f, to the governor u,-and of an edge or projection formed upon any suitable part of the valve'operating mechanism and adapted to he engaged in its lowest position by the pawl 8. Thus in the mechanism represented bythc drawing the said edge (marked by the letter a) is formed upon the end of the lever h, and the pawl s is made in shape of a hook capable of catching over the edge u. The pawl is so arranged relatively to the governor that when the engine makes the normal or a lower number of revolutions the pawl is outside of the path of the edge v, whereas when the norrual nnn'iber of revolutions is exceeded it willcome intothe said path. In the first case the lever h, after having been depressed by means of the tappet e, is free to yield to the pressure of the spring 2', acting thereon from below. The exhaust-valve is therefore opened and closed in uniform intervals, and the induction valve can play freely when the valve m is closed. A regular aspiration of full charges of combustible gas mixture by the piston con- 2 1 seems 1.

The combination, with the exhaust-valve m, rotating tappet e, an intermediatejaart or parts for transmitting motion from the tappet e to the valve m, and having an edge or projection, 0, spring 2', and governor u, of the pawl s, 'cnpable of engaging with the said edge er prosequentl y then takes place and the engine develops its maximum power. In the second case (when the pawl extends into thepa'th of the edge v) the edge, as soon as it is brought into its lowest position by the operation of the tappet e, is eaught by the pawl and maintainedin this position, the valve m being thereby kept open, while at the same'time the valve that the spring 2' presses the edge r firmly against the hook of the pawl 8 during pawl and the the time the tappet 6 does not act upon the for the purpose specified..
